That seems like a really smart way of handling it.
There are a bunch of restaurant types which just aren't that elastic to changing demand; basically anything which has a longer preparation time and is expensive enough that you can't afford to just massively overprovision. Thinking like slow-roasted meats, most soups/chilis, or fancy pastries like croissants, yeast-raised donuts, etc.
Basically any place that's serving that stuff (and legitimately making it in-house vs warming it up from frozen like a chain) is going to be done when they run out for the day. So handing out cards to locals to skip the line would be a great way of not alienating your loyal customer base.
